如何使用REST-API v2在LinkedIn上分享？

Question

我很难在linkedin上获得一份股份。我试图通过LinkedIn api v2发布一个linkedin分享，每次我发出post请求时，我都会从服务器得到一个请求超时(状态504)的回答。下面是我的代码：

$url = https://api.linkedin.com/v2/ugcPosts?oauth2_access_token=".$row[0]['accesstoken'];
$fields = '{
    "author": "urn:li:person:XXX",
    "lifecycleState": "PUBLISHED",
    "specificContent": {
        "com.linkedin.ugc.ShareContent": {
            "shareCommentary": {
                "text": "Hello World! This is my first Share on LinkedIn!"
            },
            "shareMediaCategory": "NONE"
        }
    },
    "visibility": {
        "com.linkedin.ugc.MemberNetworkVisibility": "PUBLIC"
    }
}';

$headers = array(
 'Content-Type' => 'application/json',
 'X-Restli-Protocol-Version' => '2.0.0'
 'Authorization' => 'Bearer'. $token);

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($curl);

And here is the error message :
{
  "message": "Request timed out",
  "status": 504
}

尝试下面的代码：

$url = "https://api.linkedin.com/v2/ugcPosts";

$headers = array('Content-Type: application/json','X-Restli-Protocol-Version: 2.0.0','x-li-format: json','Authorization: Bearer '.$token);

$fields = '{
    "author": "urn:li:person:*Person URN ID*",
    "lifecycleState": "PUBLISHED",
    "specificContent": {
        "com.linkedin.ugc.ShareContent": {
            "shareCommentary": {
                "text": "Hello World! This is my first Share on LinkedIn!"
            },
            "shareMediaCategory": "NONE"
        }
    },
    "visibility": {
        "com.linkedin.ugc.MemberNetworkVisibility": "PUBLIC"
    }
}';


$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
$httpCode = curl_getinfo($curl , CURLINFO_HTTP_CODE); // this results 0 every time
$response = curl_exec($curl);

if ($response === false) 
    $response = curl_error($curl);

echo stripslashes($response);

curl_close($curl);

1. 正确的API调用URL是- https://api.linkedin.com/v2/ugcPosts (您不必在URL中包含?oauth2_access_token= )
2. 由于某些原因，您定义的headers数组的格式会抛出错误。因此我对其进行了修改。
3. 人员URN ID必须替换为用户的URN ID，该ID必须由另一个API调用生成-有关如何实现此功能的更多详细信息，请参阅URN ID API。

问题已解决

在URL和头中都添加了access_token。现在代码正在运行。除此之外，一切都保持不变。

$url      = "https://api.linkedin.com/v2/ugcPosts?oauth2_access_token=".$this->accesstoken;

$headers = array('Content-Type:application/json','X-Restli-Protocol-Version:2.0.0','x-li-format: json','Authorization:    Bearer'.$this->accesstoken);
